Finding the right drill bit is essential for achieving accurate holes, faster drilling, and longer tool life. Different materials require different cutting geometries, shank designs, and tip materials. Choosing the wrong drill bit can reduce drilling efficiency, shorten tool life, or even damage the workpiece.
At DLTC, we supply professional drill bits for construction, metalworking, and industrial applications. Our product range includes SDS drill bits, straight shank masonry drill bits, and HSS drill bits, helping distributors, wholesalers, and contractors find reliable drilling solutions for different projects.
Whether you are drilling reinforced concrete, brick walls, structural steel, or aluminum, understanding the characteristics of each drill bit type will help you select the most suitable tool.
Types of Drill Bits
Not all drill bits are designed for the same material. The drilling performance depends on the bit’s cutting edge, body design, and the machine being used.
The three major drill bit categories offered by DLTC include:
- SDS Drill Bits
- Straight Shank Masonry Drill Bits
- HSS Drill Bits
Each type is designed for specific applications and delivers the best performance under the correct working conditions.
SDS Drill Bits

SDS drill bits are specially designed for rotary hammer drills and are the preferred choice for drilling concrete, reinforced concrete, brick, and natural stone. Compared with ordinary drill bits, the SDS shank allows the bit to slide inside the chuck while efficiently transferring hammer energy directly to the carbide tip.
This design improves drilling speed, reduces operator fatigue, and provides excellent durability in demanding construction environments.
DLTC supplies both SDS Plus and SDS Max drill bits in a wide range of diameters and working lengths to meet different drilling requirements.
Typical Applications
- Reinforced concrete
- Concrete walls and floors
- Brick and block
- Stone
- Construction and renovation projects
Key Features
- Carbide-tipped cutting edge
- Efficient dust removal flutes
- Fast drilling speed
- Long service life
- Suitable for professional rotary hammer drills
When selecting an SDS drill bit, choosing the correct diameter and drilling depth is just as important as selecting the right shank type. Our Concrete Drill Bit Sizes Guide can help you select the appropriate size for different construction applications.
If you are unsure whether SDS Plus or SDS Max is the better option, read our detailed comparison SDS Plus vs SDS Max to understand the differences in drilling capacity, compatible machines, and recommended applications.
Straight Shank Masonry Drill Bits

Straight shank masonry drill bits are designed for impact drills and standard electric drills. They are commonly used for drilling brick, concrete, masonry blocks, and lightweight construction materials where a rotary hammer drill is not required.
Unlike SDS drill bits, straight shank masonry drill bits use a conventional cylindrical shank, making them compatible with most portable drills. They are an economical and practical choice for general construction, installation work, and maintenance projects.
DLTC offers carbide-tipped straight shank masonry drill bits in a wide selection of sizes suitable for distributors and OEM customers.
Typical Applications
- Brick walls
- Masonry blocks
- Concrete
- Cement boards
- Home improvement
- Building installation
Key Features
- Carbide cutting tip
- Straight shank design
- Compatible with standard impact drills
- Accurate positioning
- Stable drilling performance
Choosing the correct drill bit diameter is essential when drilling masonry materials, especially when installing anchors or expansion bolts. You can refer to our Concrete Drill Bit Sizes Guide to quickly identify the appropriate drill bit size for different drilling tasks.
HSS Drill Bits

High Speed Steel (HSS) drill bits are among the most versatile drilling tools and are widely used for drilling metal, wood, plastic, and other soft materials. Compared with masonry drill bits, HSS drill bits feature a sharp cutting edge designed to produce clean and accurate holes in metalworking applications.
Depending on the material and coating, HSS drill bits can be used for drilling mild steel, stainless steel, aluminum, copper, wood, and plastic. Common material grades include M2 and M35, with cobalt-containing M35 drill bits offering improved heat resistance for tougher metals.
DLTC supplies HSS drill bits in multiple sizes and specifications for industrial distributors, wholesalers, and OEM customers.
Typical Applications
- Mild steel
- Stainless steel
- Aluminum
- Copper
- Wood
- Plastic
- Sheet metal fabrication
- General maintenance
Key Features
- Precision ground cutting edges
- High-speed steel construction
- Excellent wear resistance
- Suitable for manual drills and drill presses
- Available in multiple coatings and material grades
If you are drilling stainless steel, selecting the correct drill bit material is critical for improving tool life and drilling efficiency. Our guide on Best Drill Bits for Stainless Steel explains which drill bits perform best under different working conditions.

How to Choose the Right Drill Bit
Choosing the right drill bit depends on three main factors: the material you are drilling, the drilling machine you are using, and the hole size required. Using the wrong drill bit can reduce drilling efficiency, damage the cutting edge, or shorten the tool’s service life.
The table below provides a quick reference for selecting the appropriate drill bit.
| Material | Recommended Drill Bit | Common Drill |
|---|---|---|
| Reinforced Concrete | SDS Drill Bits | Rotary Hammer Drill |
| Concrete & Brick | Straight Shank Masonry Drill Bits | Impact Drill |
| Mild Steel | HSS Drill Bits | Electric Drill |
| Stainless Steel | HSS Cobalt Drill Bits | Drill Press / Electric Drill |
| Aluminum | HSS Drill Bits | Electric Drill |
| Wood | HSS Drill Bits | Electric Drill |
For projects involving reinforced concrete, an SDS drill bit generally provides faster drilling speed and better impact performance than a standard masonry drill bit.
Likewise, HSS drill bits are the preferred choice for drilling metal because they are designed with cutting geometries suitable for steel and non-ferrous materials rather than concrete.
Common Applications of Different Drill Bits
Although all drill bits are designed to create holes, each type is optimized for specific industries and working environments.
